+14. Add native Directory and TermDocs implementations that work under
+ GCJ. These require GCC 3.4.0 or later and have only been tested
+ on Linux. Use 'ant gcj' to build demo applications. (cutting)
+
+15. Add MMapDirectory, which uses nio to mmap input files. This is
+ still somewhat slower than FSDirectory. However it uses less
+ memory per query term, since a new buffer is not allocated per
+ term, which may help applications which use, e.g., wildcard
+ queries. It also should, in theory, someday be faster. A
+ downside is, due to limitations of the nio APIs, this does not
+ work with indexes containing files larger than 2^31 bytes. (cutting)
+
+16. Optimize the performance of certain uses of BooleanScorer,
+ TermScorer and IndexSearcher. In particular, a BooleanQuery
+ composed of TermQuery, with not all terms required, that returns a
+ TopDocs (e.g., through a Hits with no Sort specified) runs much
+ faster. (cutting)
